If an amplifier becomes non-linear, the output signal would:
- A become distorted
- B be reduced to zero
- C cause oscillations
- D overload the power supply
Correct answer: A — become distorted. From the official ISED question bank, verified word for word.
Why
When an amplifier becomes non-linear, it fails to copy the input signal perfectly, causing the output waveform to change shape and sound garbled, which is called distortion. The full explanation — and one for every question — is in Pro.
